Description of key information

One key study was available using the read-across substance glycerol as test substance and Scenedesmus quadricauda as test species. No effects were seen at 10000 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
10 000 mg/L

Additional information

The effect of glycerin exposure over an 8 day exposure period was examined with Scenedesmus quadricauda. Differences in turbidity were measured after 8 days and values greater than 3% (EC3) were considered significant. The EC3 was > 10000 mg/L.
